8-1/4 bearing pre load tool
I found a big bolt I had in my bolt bins that was a little bit to large to fit in the adjusters. I took and ground down the flat sides at a taper angle til it would fit the adjuster but not go thru it. I then used a 7/8" socket that just fit the threaded end of this large bolt. I then welded it to the bolt. I use a long 1/2" extension thru the tube openings to set backlash. If I were home I would take a picture of it.
